Do Not Respond to Anger

I man once cursed the Buddha to his face. The Buddha only smiled. The man became even more incensed and asked, "Why don't you respond?" The Buddha replied, "If someone refuses a gift, it must be taken back by the one who offered it." The Buddha then recited this verse:

"For those with no anger,
how can anger arise?

When you practice deep looking and master yourself,
you dwell in peace, freedom, and safety.

The one who offends another after being offended by him,
harms himself and harms the other.

When you feel hurt, but do not hurt the other,
you are truly victorious.
Your practice and your victory benefit both of you.

When you understand the roots of anger in yourself and in the other,
your mind will enjoy true peace, joy, and lightness.

You become the doctor who heals himself and heals the other.

If you don't understnad,
you will think not getting angry to be the act of a fool."
